RMM-1 TO RMM-IV CONVERSION
(Parts Needed)

The microcomputer sends commands to the light drive module (LDM), which in turn controls the on/off and dimming range of the light fixture. Note: The microcomputer "reads" the presence of the LDM by detecting the operation of a small light emitting diode within the optocoupler on the LDM. If the LDM is not present (or the optocoupler is defective or wiring is open) the microcomputer will assume that no light fixture is attached to the fan and will operate differently. On power up, the fan will begin accelerating in speed automatically until the user operates the fan button to select the desired speed. Also, the microcomputer will not allow any of the special programs to be selected.

The microcomputer also controls the direction of the fan through a small reversing relay mounted on the RMM-I circuit board.

To control motor speed, the microcomputer selects one of six outputs, each of which turns on an electronic switch known as a triac. These six triacs are located on the RMM-I circuit board. In high speed, a triac drives the motor directly. In all other speeds, a triac drives the motor through one or all five dropping resistors contained within the BFR-1. This reduces power to the motor while maintaining a pure sine wave drive.

The BFR-1 is a flexible, printed circuit resistance network of five resistors for the motor drive. The BFR-1 also contains two power resistors used in the power supply circuitry for the RMM-I.
